    Jewell, Sharon A.; Cornford, Stephen Leslie; Sambles, J. Roy (American Institute of Physics, 2007)
    A liquid crystal filled Fabry-Pérot etalon has been constructed to control the resonant transmission of electromagnetic radiation over the visible range of the spectrum. This has been achieved through the use of a 1.5 µm ...
  • Dynamic inundation simulation of storm water interaction between sewer system and overland flows 

    Hsu, Ming-Hsi; Chen, Shiuan‐Hung; Chang, Tsang-Jung (Taylor & Francis / Chinese Institute of Engineers, 2002)
    An improved urban inundation model, coupling a 2D non‐inertia overland flow model with a storm water management model, is adopted to simulate inundation in urban areas. The model computes, not only the overland runoff and ...

    The switch-off dynamics of a 180° supertwisted nematic (STN) are explored in detail by using a convergent beam system and the fully leaky guided-mode technique. From the dynamical guided-mode data and using the Ericksen–Leslie ...
  • Dynamics of coupled cell networks: synchrony, heteroclinic cycles and inflation 

    Aguiar, M.; Ashwin, Peter; Dias, A.; Field, M. (Springer Verlag, 2011)
    We consider the dynamics of small networks of coupled cells. We usually assume asymmetric inputs and no global or local symmetries in the network and consider equivalence of networks in this setting; that is, when two ...

  • Dynamics of two laterally coupled semiconductor lasers: strong- and weak-coupling theory. 

    Erzgraber, H.; Wieczorek, Sebastian; Krauskopf, Bernd (American Physical Society, 2008)
    The stability and nonlinear dynamics of two semiconductor lasers coupled side to side via evanescent waves are investigated by using three different models. In the composite-cavity model, the coupling between the lasers ...
  • Dynamics on networks of cluster states for globally coupled phase oscillators 

    Ashwin, Peter; Orosz, Gábor; Wordsworth, John; Townley, Stuart (Society for Industrial and Applied Mathematics, 2007)
    Systems of globally coupled phase oscillators can have robust attractors that are heteroclinic networks. We investigate such a heteroclinic network between partially synchronized states where the phases cluster into three ...
  • Early Warning System for Bathing Water Quality

    Poster describing use of Artificial Neural Networks (ANN) in a Receiver-Operating Characteristic (ROC) scenario to predict bathing water quality exceedances at beaches in the SW UK.
  • The Earth as an extrasolar transiting planet: Earth's atmospheric composition and thickness revealed by Lunar eclipse observations 

    Vidal-Madjar, A.; Arnold, L.; Ehrenreich, D.; Ferlet, R.; Lecavelier des Etangs, A.; Bouchy, F.; Segransan, D.; Boisse, I.; Hebrard, G.; Moutou, C.; Desert, J.-M.; Sing, David K.; Cabanac, R.; Nitschelm, C.; Bonfils, X.; Delfosse, X.; Desort, M.; Diaz, R.F.; Eggenberger, A.; Forveille, T.; Lagrange, A.-M.; Lovis, C.; Pepe, F.; Perrier, C.; Pont, F.; Santos, N.C.; Udry, S. (EDP Sciences for European Southern Observatory (ESO), 2010)
    Context. An important goal within the quest for detecting an Earth-like extrasolar planet, will be to identify atmospheric gaseous bio-signatures. Aims. Observations of the light transmitted through the Earth’s atmosphere, ...
  • Economical carbon and cellulosic sheet moulding compounds for semi- and non-structural applications 

    Evans, Kenneth E.; Brookbank, Paul A.; Savage, Luke (SAGE Publications, 2015)
    The use of discontinuous carbon fibre plastics (DCFP) in automotive applications is increasing. The material offers a light weight and stiff alternative to conventional short-fibre glass-reinforced composites such as sheet ...
  • Edges of Mutually Non-dominating Sets 

    Everson, Richard M.; Walker, David J.; Fieldsend, Jonathan E. (ACM, 2013-07)
    Multi-objective optimisation yields an estimated Pareto front of mutually non-dominating solutions, but with more than three objectives understanding the relationships between solutions is challenging. Natural solutions ...
  • Effect of a Jurassic Oceanic Anoxic Event on belemnite ecology and evolution. 

    Ullmann, CV; Thibault, N; Ruhl, M; Hesselbo, Stephen P.; Korte, C (PNAS, 2014-07-15)
    The Toarcian oceanic anoxic event (T-OAE; ∼ 183 million y ago) is possibly the most extreme episode of widespread ocean oxygen deficiency in the Phanerozoic, coinciding with rapid atmospheric pCO2 increase and significant ...
